There have been numerous reports of UFO sightings and artifacts found from Roswell to Russia, but proof aliens exist can come from beneath the waves as well. Perhaps alien spacecrafts should be renamed "unidentified floating objects," since so many UFO sightings take place around bodies of water – and sometimes, aliens are even captured on camera.

With the impressive abilities of Google Earth, anyone can explore parts unknown and make amazing discoveries. Several anomalies that appear in this list were found after people carefully combed the virtual ocean floors. Structure-like objects have been discovered all over the world, ranging from buildings to what may actually be spacecrafts.

Above water, numerous stories of alien encounters include UFOs entering and exiting lakes and oceans, prompting researchers to believe secret alien bases may lie below. These stories of creepy UFO sightings come from both above and below the waves and may make you consider the world's large bodies of water in a new light.

Take a look at these photos that seemingly capture underwater UFOs, and vote up the tales that have you convinced aliens walk among us.

An Object Resembling The "Millennium Falcon" Was Discovered in The Baltic Sea

At the bottom of the Baltic Sea, off the coast of Sweden, lies an unusual object that almost resembles the Millennium Falcon. It was discovered in 2011 by a group of Swedish men looking for treasure, and according to their sonar readings, the anomaly measured about 200 feet wide. A geologist collected samples and believed the formation is made of metal and not a natural phenomenon.

Strangely enough, the anomaly also affects electrical equipment, as one diver recalled:

“Anything electric out there, and the satellite phone as well, stopped working when we were above the object. And then when we got away about 200 meters, it turned on again, and when we got back over the object it didn't work."

A Man-Made Structure Was Found In The Mysterious Dragon's Triangle

A Japanese diver discovered a strange man-made structure in the waters off Yonaguni in 1985, but it wasn't until a researcher began claiming it was the remains of an ancient civilization in 1996 that people began paying attention. Some brushed it off as a natural ocean occurrence, but the fact that the structure is 490 feet wide, 90 feet tall, and features smooth planes with right-angled edges makes that assumption questionable.

The structure is also located in an area called the Dragon's Triangle, an area known for ship and airplane disappearance myths similar to those of the Bermuda Triangle. Additionally, an old Japanese legend claims a large craft and a woman who spoke an unknown language once washed up on shore near the Yonaguni monument.

An Incredibly Large Pyramid Structure Was Discovered Off Mexico's Western Coast

In June of 2016, researcher Marcelo Igazusta spotted an odd beam of light coming from the ocean off Mexico's west coast and decided to check it out. Using Google Earth, a large pyramid structure – thought to measure about 8.5 miles wide at the base – was found.

Rather than some sort of base, researchers believe the pyramid may be an alien spacecraft. UFO Sightings Daily blogger Scott C. Waring noted, "Humans never could have built such a construction. Only aliens could accomplish making such a massive structure."

The World's Oldest Computer Was Found In A 19th Century Shipwreck

A shipwreck is not the most likely place one would find an ancient computer, but around 1900, a strange technological artifact was found in the wreckage of the Antikythera. Divers salvaged 82 separate pieces of the machine which is thought to be an analog computer used for calculating the positions of the stars.

Its housing was composed of wood and held about 30 gears made of bronze. The machine is thought to be the oldest device ever found that used a gear system to function. While scholars date the machine back to 100 BCE, one historian believes it is even older.
